Yesterday I saw an ENT consultant as I have been having blood in the morning in my saliva. He popped in a thin scope and had a look at my throat and nose etc. He said I have a growth quite high up behind my nose. I asked him if it was a polyp and he said it's more adenoid related. Then he said I would be receiving a letter with an appt for a biopsy and put urgent on the form. Is this anything to worry about? Could it be something and nothing?
